欧洲蓝茉莉任一种生长于热带的白花丹属植物,开成串的色彩各异的花朵。
直到16世纪,英国人才发现大量纯石墨矿藏,当时称为「黑铅」。
1·BG 6# blast furnace bosh area had been broken out , the bosh inner used the high thermal conduction and plumbago carbon brick replace the micropore carbon brick, and the results are obviously better.
本钢6#高炉炉腹区域烧穿,炉腹内衬采用高导热、高体密石墨碳砖代替原烧成微孔铝碳砖,实施效果良好。
2·The copper dressing electrode is preferred to plumbago one as it will result in unstable discharge between the two electrodes.
紫铜电极相比石墨电极能有效避免拉弧现象,产生稳定的电火花放电;
3·The plumbago balls were counted and defects were tested by this system, and the results showed that the system is with good test capability.
系统完成后,对石墨球进行了过球计数和缺陷检测的实验,结果表明系统具备良好的检测性能。
